1. Kainic Acid: An Excitatory Amino Acid Receptor Agonist Selective for Kainate Receptor Subtype

    OVERVIEW Kainic Acid is a marine product, derived from the red marine alga Digenea Simplex. Kainic Acid is an excitatory amino acid receptor agonist selective for kainate receptor subtype; conformationally restricted analog of L-glutamic acid. Kainic acid is a potent central nervous system stimulant, and has been developed as the prototype neuroexcitatory amino acid for the induction of seizures in experimental animals, at a typical dose of 10-30 mg/kg in mice. Kainic acid is neuroexcitotoxic and epileptogenic, acting through specific kainate receptors.
  2. A23187: A Carboxylic Acid Antibiotic Which Simultaneously Uncouples Oxidative Phosphorylation and Inhibits ATPase

    OVERVIEW A23187 is a carboxylic acid antibiotic which simultaneously uncouples oxidative phosphorylation and inhibits ATPase of rat liver mitochondria incubated in a magnesium-free medium. The antibiotic acts as a freely mobile carrier to transport calcium and magnesium, but not potassium, from an aqueous medium buffered at pH 7.4 into a bulk organic phase. A23187 causes a progressive release of endogenous...
